Xbox One and PS4 fans are crying out for these critically-acclaimed Xbox 360 and PS3 games to be remastered.

The Mass Effect Andromeda Strike Missions will exist in parallel to the main campaign - but be separate and optional missions players can take on.

Frazier said: "Some of these missions are called 'Apex Missions.' They're generally a little harder. You can send your teams to do them, but it's going be really hard for them unless you've really leveled up your teams.

"Or you can do it yourself in multiplayer. You can just hit a button, it'll quick-save your single-player game [and] launch you directly into multiplayer where you can solo if you want, you can match-make with friends, [or] you can do a public game and match-match with strangers."

Mass Effect Andromeda lead developer Frazier told GameSpot the transition between the multiplayer Strike Missions and the single player campaign will be seamless.

He added that these multiplayer missions will be appropriate to where you're at in the single player campaign too.

He said: "If it says it's a night mission on a certain map against Kett for this objective, that's what the mission will actually be."
